Heat likely won't be an Independence Day health concern as locals on Monday flock to Taste of Chicago and lakefront beaches.

Monday's high of 85 falls short of the near-record temperatures that plagued Memorial Day weeks ago, causing several heat-related hospitalizations and reportedly closing North Avenue Beach.

Fourth of July temps will even fall in time for fireworks at Navy Pier, according to the National Weather Service, dipping as low as 66.

Saturday's 10:15 p.m. fireworks display went off smoothly as a prelude to Monday night's big show. Chicago Police said Friday they expect smaller crowds for the main event, but they're not letting up on security just in case.

"We can move on the fly," Police Supt. Garry McCarthy said Friday. "We are well prepared."

McCarthy announced earlier this month tighter security at Taste, including more undercover cops and extra video surveillance. With recent mob attacks in Streeterville and at CTA stations downtown, McCarthy said officers also will be stationed at train stops and outside the festival.

During last year's Fourth of July light show at Navy Pier, the space reached capacity two hours before the fireworks began. By 7:20 p.m., the Pier was closed to additional pedestrian traffic.

Elsewhere on the Fourth, Gov. Pat Quinn plans to march in the Des Plaines Independence Day Parade and is expected to sign legislation to help Illinoisans better participate in state government.

Cook County President Toni Preckwinkle marches in the Hyde Park Fourth of July Parade at 11 a.m. and in Evanston's parade at 2 p.m.
